Two racing cars `'A'` and `'B'` having masses `'M'` and `'2m'` respectively start running from the starting line on a horizontal plane.Both cars `'A'` and `B'` have same speed `'V'` which is constant through out the journey. The track of the two cars are the arcs of concentric circle having centres `O_(1)` and `O_(2)` as shwon in figure with data. The friction coefficient of the two cars with the road is same. There is a finishing line at the end of the arc. Using these informations solve the following questions.

The magnitude of relative acceleration of two cars when car `'A'` just reaches the end of circular arc of radius `Y`.
